@Zhenya Kovalyov How often can I make the requests in my Python code in a second and which function should I use out of the following?1) ek.news_request() 2) ek.json_requests() 3) ek.send_json_request()

The method name is get_news_headlines. See "Eikon Data APIs for Python - Reference Guide" under the Documentation tab on Eikon Data APIs page on this portal for documentation and this tutorial for examples.For guidance on throttles and retrieval limits see this document.
